EDWARD L. ALLEN, OF FAIR HAVEN, VERMONT.

IMPROVED VESSEL FOR PETROLEUM, 31.0.

Speciiication forming part of Letters Patent No. 54,657, dated May 8,1866.

To all whom it may concern:

Be it known that I, EDWARD L. ALLEN, of Fair Haven, Rutland county,Vermont, have invented a new and useful Improved Safe for HoldingKerosene and other Volatile Oils; and I hereby declare that thefollowing is a invention, reference being had to the accompanyingdrawings and the letters of reference marked thereon, which drawingsmake a part of this specifi cation.

Like letters represent and refer to like or corresponding parts.

Figure lis a view of my improved safe, showing the exterior constructionof the same. Fig. 2 is a vertical section of my said improved safe,showing the interior construction and the mode of operationthereof. u

The nature of my invention consists in constructin g a receptacle forkerosene and other volatile oils entirely of metal, substantially ashereinafter described, so as eectually to preventu loss by leakage orevaporation, and in entirely surrounding said metal receptacle with atight wooden casing firmly joined at the corners, as hereinafterdescribed, for the purpose of supporting the bottom and sides thereofand preventing the same from being parted or ruptured by the pressure ofthe oil therein contained.

It also consists in so constructing the bottom of said receptacle thatit shall incline downward in a conical or other form or shape to asingle point, at which point a dischargepipe is inserted, in the mannerand for the purposes hereinafter described and set forth.

Having thus described the nature of my said invention, and to enableothers skilled in the art to which it relates to make andV use the same,I will here proceed to describe the construction and operation thereof,which is as follows, to wit:

It has been ascertained by experience that kerosene and other oils ofthe same penetrating and volatile nature cannot be safely kept inbarrels or any other wooden receptacles, because they will inevitablyescape through the joints of the vessel and the pores of the wood, thuscausing a heavy loss by leakage and evaporation. To avoid this Iconstruct the inner receptacle, B, Fig. 2, of any metal suitable forthat purpose, though I have used zine as preferable to any other. Thebottom is constructed in the manner hereinafter described. For the sakeof both economy and convenience, I construct this receptacle of 'platesof metal much too thin to bear the pressure of the iiuid when filledwithout outside support. Entirely around this inner metal receptacle Iconstruct the wooden box or casing A, Fig. 2, tightly inclosing the saidmetal receptacle and rmly joined at the corners by dovetails, as shownat H, Fig. 1. By this means the said wooden casing gives a firm andsolid support to the sides and bottom of the receptacle and prevents anyparting or rupture from the pressure of the oil when it is filled. Thisis different from a wooden receptacle lined with metal,in asmuch as themetal is not attached to the wood, but a perfectly tight reservoir ofmetal is rst constructed` and then the wooden casing built around it tosupport the same in the manner aforesaid. y

My improved safe is principally intended for the use of dealersretailing kerosene or similar oils, and it is found that when such oilsstand in large quantities for a length of time there is a sedimentdeposited which ren ders it necessary to frequently clean the vesselcontaining the same, and which corrodes metals with which it is incontact. To remedy this I construct the bottom of the said receptacle E,Fig. 2, in such a manner that it inclines downward from each sfide tothe center in a conical shape or form, at which point I place thedischarge-pipe F, to which is attached the stop-cock G, Fig. 1. Thispoint need not be at the center, but may be at any other point in thebottom. It is sufficient, if the said bottom is so constructed, that itinclines to the entrance of the discharge-pipe; nor is this deviceconfined to a square-shaped receptacle, but is equally applicable to oneof a cylindrical or other different shape. The advantage of thisarrangement is that, as the oil is drawn off from time to time throughthe discharge-pipe, the sediment, which always settles to the lowestpoint, is drawn off with it, thus preventing the corrosion of the metaland thenecessity of cleaning. By this means, also, the safe can beentirely emptied without the necessity of tipping or handling the same.

The cover D, I construct according to the patent of M. Ludlum, grantedJuly 5, 1859,

which shuts closely and prevents evaporation, and also prevents theoffensive odor of the oil from escaping.

Having thus described the construction and operation of my saidinvention, what I claim as my invention, and desire to secure by LettersPatent, is-

1. The employment of the wooden box or casing A, in combination With themetal receptacle B and surrounding the sume, in the manner and for thepurposes hereinbefore described and set forth.

2. Ihe employment, in a reservoir for the reception of kerosene andother volatile oils, of the bottom E, so constructed es to inclinedownward in e conical or other shape or form to the point where thedischarge-pipe F is inserted, substantially in the manner and for thepurposes herein described and set forth.

In testimony whereof I have, on this 14th day of April, A. D. 1866,hereunto set my hand.

EDWARD L. ALLEN. Y
